New method for preparing N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine

-

Paragraph 0015-0020, (2019/10/01)

The present invention relates to a new method for preparing N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine, wherein 1,3-dimethyl-2-imidazolidinone or 1,3-dimethyl-tetrahydro-2-pyrimidone is used as a raw material, a suitable alkali is added, and a heating ring-opening reaction is perform to prepare N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine. In the prior art, the conventional method performs alkylation by using the amine as the raw material to generate more by-products. According to the present invention, the method completely avoids the problem in theprior art, has characteristics of simple operation, high yield, less three-waste and high product purity, and is suitable for industrial production.

Continuous chemoselective methylation of functionalized amines and diols with supercritical methanol over solid acid and acid-base bifunctional catalysts

Oku, Tomoharu,Arita, Yoshitaka,Tsuneki, Hideaki,Ikariya, Takao

, p. 7368 - 7377 (2007/10/03)

The selective N-methylation of bifunctionalized amines with supercritical methanol (scCH3OH) promoted by the conventional solid acids (H-mordenite, β-zeolite, amorphous silica-alumina) and acid-base bifunctional catalysts (Cs-P-Si mixed oxide and γ-alumina) was investigated in a continuous-flow, fixed-bed reactor. The use of scCH 3OH in the reaction of 2-aminoethanol with methanol (amine/CH 3OH = 1/10.8) over the solid catalysts led to a significant improvement in the chemoselectivity of the N-methylation. Among the catalysts examined, the Cs-P-Si mixed oxide provided the most efficient catalyst performance in terms of selectivity and reactivity at 300 °C and 8.2 MPa; the N-methylation selectivity in the products reaching up to 94% at 86% conversion. The present selective methylation was successfully applied to the synthesis of N-methylated amino alcohols and diamines as well as O-methylated ethylene glycol. Noticeably, ethoxyethylamine was less reactive, suggesting that the hydroxy group of the amino alcohols is a crucial structural factor in determining high reactivity and selectivity, possibly because of the tethering effect of another terminus, a hydroxo group, to the catalyst surface. The magic-angle-spinning NMR spectroscopy and X-ray diffraction analysis of the Cs-P-Si mixed oxide catalyst revealed that the acidic and basic sites originate from P2O5/SiO2 and Cs/SiO2, respectively, and the weak acid-base paired sites are attributed to three kinds of cesium phosphates on SiO2. The weak acid-base sites on the catalyst surface might be responsible for the selective dehydrative methylation.
